Select the right one among various RTDs on the basis of temperature range and accuracy requirement.
RTDs work best under the temperature range of -200ºC-850ºC.
If you need a higher level of accuracy then RTD is better option.
RTD’s are commonly used in applications where repeatability and accuracy are important considerations. Properly constructed Platinum RTD’s have very repeatable resistance vs. temperature characteristics over time.
RTD can be used where Stability, Sensitivity and Linearity is important parameter.
RTD Design selection:
Good heat transition between sheath and the temperature probe to permit short response time and high measuring accuracy.
RTD designshould withstand the process vibrations.
